I've tried a bunch but I was on beans for a while and it was great in many ways (customization, battery, multi-window, etc.) but i did notice a bit of chopiness and also some games seemed to be running worse than i thought they should be. i recently switched to cleanrom5.6 with stock kernel and nova launcher and it is working great! It is smooth and all of the games and apps i have work well. I do miss the cool perks of beans or other ROMs but having everything work well is great. As usual, I will probably get sick of the stock experience soon and go to yet another ROM but for what its worth cleanROM 5.6 is running great with no problems.
